Decade Mobilizes Drill for Phase I Drilling at the Bonaparte Property

Stewart, British Columbia--(Newsfile Corp. - August 6, 2026) - Decade Resources Ltd. (TSXV: DEC) ("Decade" or the "Company") announces that it has mobilized a drill to the Bonaparte copper-gold property, located approximately 50km north of Kamloops, B.C., within the Kamloops Mining Division. The property consists of 4 mineral tenures (claims) totaling 4149.63 hectares in size.

The property has various target areas including:

Cu/Au/Mo porphyry potential

Bulk-tonnage RIRGS target with high grade gold results in historic drilling, trenching, underground exploration

High grade gold-copper low sulphidation epithermal veins system.

Ed Kruchkowski, President of Decade Resources , stated:

"In late July, a contract sampling crew completed a soil sampling survey over the south part of the indicated IP anomaly resulting in the collecting of over 750 soil samples and 30 rock samples. The rocks were cut with a diamond saw to provide smooth surfaces for study. In examination of the rock samples, many were hornfels which is a fine-grained metamorphic rock without obvious foliation that forms by heat from a nearby magma. What was of great interest was the fine fracturing in this hornfels containing fine veinlets of chalcopyrite and pyrite. These rocks are interpreted as being over 275 m above the chargeability anomaly (source postulated to be altered and mineralized intrusive). The Company feels that this is further evidence of all the positive indicators for a buried porphyry copper-gold system as indicated by geophysical data (chargeability high and resistivity high), geochemical data MMI (Mobile Metal Ions) copper-gold anomalies as well as soil anomalies and outcrop exposures with copper-gold values in the Discovery Area."

Discussion of Bonaparte

In 1994, from within the property area, a 3,700 metric ton bulk sample of mineralized vein material from surface trenching to a vertical depth of 12.2m from an open cut on the Nutcracker, Owl, Grey Jay and Crow vein systems, with an average grade of 25.4 g/t Au produced 3,160 ounces of gold. In 2010 a small bulk sample from the Crow Vein was shipped to the Kinross Mill in Republic, Washington. The 364-ton sample assayed 16.3 g/t Au (0.475 oz/t Au), yielding 161.95 troy ounces of gold. The above results are both from the BC Minfile and a 43-101 report by R. Kemp. The Company thinks that these results can be relied on. The previous operator had a 10,000 tonne extraction permit which would include both mineralization and wall rock. This sample was extracted from an area 20m wide along the closely spaced veins. This implies a grade of 0.317 oz/tonne or 9.86 g/t over this 20 m wide zone, offering great potential for delineating a substantial gold system.

In 2013 to 2014, historic IP surveys, existing geophysical and geological data indicates the potential for a large porphyry system situated approximately 1km South of the original Discovery Zone. A second and smaller zone also appears to lie below the original Discovery Zone at depth. Data indicates the larger southerly body begins near the surface and gradually increases in size to approximately 3km wide x 2km wide at approximately 275m depth and then gradually decreases in size to a depth of 500m which is the extent of the geophysical data. The overlapping low resistivity and high chargeability anomalies suggest there is a very good probability that they represent mineralized zones.

Indicated Resistive (IP) anomalies which are considered high-priority drill targets that may indicate the presence of silicification, quartz veining, or potassic alteration—features that commonly host disseminated gold or copper mineralization. These Resistivity anomalies coincide with High Chargeability anomalies, suggesting a silica-rich, resistive host rock containing disseminated conductive sulphides. This interpretation is in line with comments from geological examinations by geologists from the British Columbia Geological Survey, Ministry of Energy, Mines and Natural Gas state: " We speculate that the Bonaparte deposit represents an upper level of a buried porphyry system ." Reference for this is located in: Bonaparte gold: another 195 Ma porphyry Au-Cu deposit in southern British Columbia? James M. Logan and Mitchell G. Mihalynuk, British Columbia Geological Survey, Ministry of Energy, Mines and Natural Gas, page 71, 2013.

The IP anomalies appear to start at approximately 300m depth and extend beyond 500m in depth as per the 43-101 report by R. Kemp. The Company plans a minimum of 3000m of drilling consisting of 5-6 holes, each 500m or more in length.

The potential of the project is enhanced by its regional setting as the project is located in a structural trend of producing mines and deposits in the Quesnellia terrane, and is on a structural, stratigraphic and plutonic trend in common with Afton.

2026 Drilling

The Company plans to use a drill capable of drilling NQ sized core to at least 500m within the holes. Priority is in areas where independent evidence overlaps: MMI Cu/Au anomalies, soil Cu/Au geochemistry anomalies, chargeability, resistivity, and access.​

The first hole is planned to test the chargeability anomaly below the Discovery area. ​ This is designed to test whether the Discovery–Cooler Creek corridor represents a connected mineralized system rather than isolated surface anomalies.​ The second hole approximately 500m east will tests the MMI anomalies, as well as a resistivity high and chargeability-resistivity transition east of Discovery.​

In total 3000m is planned for the Phase I drilling in 6 holes. Location of holes 3 to 6 will be determined after completion of Holes 1 and 2.

Brush and Shine a First Nation contracting company owned by a Tk̓emlúps te Secwépemc band member based in Kamloops BC. has been contracted to provide fire suppression services during the drilling.
